When you raise/lower the car, the track change from lifting the car puts a substantial side-load on the tires, no effect. The car can slide sideways on the tires, on rough pavement, no damage to the suspension. To damage/bend something, it is my experience that you must create side-loads that far exceed what the tire's traction can provide.

Why did he loosen/tighten the bolts? Just to re-torque? Did he test-drive it for you?
